The reference character ed portions 36 of the shaft 31 are digging 40 13 designates a. frame suspended from the elements 37, which are angularly disposed main frame 10. The frame 13 is adapted to in such a manner that when they engage the carry a motor of any suitable type not material operated on the same is moved cen-. shown trally of the device to a position where it The motor shaft is designated by the refwill be scooped up by the buckets 35 and 45 erence character 14, and extending around .elevated the desired height dependent upon a suitable pulley 15 carried'by said motor the adjusted position of the frame 27. shaft is a chain 16, shown in dotted lines in These digging elements 37 are angularly Figure .3. and said chain is adapted to drive disposed with relation to the longitudinal a gear wheel 17, which in turn meshes with center of the frame 10, and also with respect m a gear wheel 18.which meshes with a gear to each other. so that as the shaft 21.1 rotates,

wheel 19 carried by a shaft 20 shown in full the said digging elements 37 will succeslines in Figures 3 and 1. This train of gearsively engage the pile of material operated iug forms the means by which the shaft 20 upon as above described. is rotated and keyed to the shaft 20, as at 21, The reference character 38 designates a construction it will be-seen that frame, which is connected at its upper end to the conveyer frame 27 andhas its lower end rovided with a perforation for the reception of the free end of the shaft extensions' 36.

The upper shaft 30 is provided with a sprocket Wheel 39, and passing-around said sprocket wheel 39is a driving chain 40,said driving chain also passing around a sprocket Wheel 41 carried bya transversely extending shaft 42. Carried by the transversely extending shaft 42, is a sprocket wheel 43, and passing therearound is a chain 44, operatively'connected with a sprocket 43 which is adapted to be rotated by a motor, not shown, hereinbefore referred to. By this the conveyer chain members 34 are driven by rotation of the shaft 30, which is obtained through the medium of the chain 40, the sprocket wheel 41, the sprocket wheel 43, the chain 44 and the sprocket 43.

The mechanism for propelling the loader at reduced speed and in a. direction in which it will be continuously moved into the pile of material being operated upon, is clearly shown in Figures 3 and 4, and with reference to said figures, it will be seen that the shaft 42 is provided with a bevel gear 45, which is fixed thereto and adapted'to rotate therewith.

' Secured to one of the stanchions 29 is a bracket bearing 46 and suspended in said bracket bearing 46 and so arranged therein as to have a slight swinging movement, is a vertical shaft 47 The upper end of the shaft carries a bevel gear 48, which is adapted to rotate therewith, and secured near.

its lower end to the shaft 47, is a worm gear 49. p

Mounted on the frame 10, 1s a cam member 50, which is operated by, means of, a

handle51, and pivotally connected to said cam, asat 52, is a. collar 53, the said collar being adapted to receive the lower end of the shaft47.

By this construction, it Wlll be seen that as the cam handle 51 is rocked, as shown by the arrow and the dotted lines in Figure 3,

the worm gear 49 will be moved into and out of engagement with the gear 54, which is carried by the shaft 23, and is adapted to rotate the same, and through the medium of the pinion 27 heretofore mentioned, drive the traction wheels 12.

Having thus described the invention, the

' operation thereof is as follows When the pinion 22 is engaged with the externalgear 24, the machine will travel in the forward direction, and when the pinion 22 is engaged with the internal gear 25, the direction of travel of the machine is reversed and the speed thereof is' materially decreased. This method of propulsion is intended only for transportation of the manot in use.

In order that .the buckets may at all times operated upon.

chine from place to place when thesame is be in a position convenient to the material to be elevated, it is desirous that the machine be moved at a considerably reduced speed toward the pile of material continuously during the operation of the elevator .flight, .and this is accomplished by movement of the cam handle 51 to the dotted line position in Figure 3, in which position the wormgear 49 enga the gear 54 and drives the tractionw eel. 12 in the reverse direction, it being understood, of course,

that the pinion 22 will have been first adjusted to the neutral position shown in F ig ure- 4. Inasmuch as it is only desirous to drive the machine atthis greatly reduced speed and in a reversed dlrection during the operation thereof upon a pile of material, 'the last mentioned mechanism is so arranged thatit derives its power from the conveyer or elevator-driving mechanism. and would, therefore, only be operable dur ing the operation of said conveyer or elevator, and is likewise dependent thereon for its power.

As the machine is continuously driven into the pile of material to be operated upon, it will be seen that the digging elements 37 will segregate the material and move it forwardly with respect to the travel of the machine to a point approximately parallel with the longitudinal center of the machine, in which position it will be engaged by the buckets 35 of the conveyer or elevator and removed.

By this construction and arrangement of parts, it is obvious that the machine herein described is practically continuous in its operation and is capable of greater capacities thanare machines in which it is necessary to stop the elevating mechanism in order that they may be adjusted from time to time with relation to the pile of material I claim:
